Answer:

f^-1(x) = [(x + 1)/2]^⅓

Step-by-step explanation:

y = 2x³ - 1

Make x the subject

2x³ = y + 1

x³ = (y + 1)/2

x = [(y + 1)/2]^⅓

Interswitch variables

f^-1(x) = [(x + 1)/2]^⅓

Lelu [443]

Answer:

n-4(32.5) > 300;n > 430

Step-by-step explanation:

Simplify: 300 = 4n - 130

Add 130 to each side. 430 = 4n

Divide by 4 on each side: 107.50= n

300 = 4(107.50) - 130? True

This tells us he must be paid $107.50 to make $300 exactly. Anything larger than $107.51 and up will make more than $300.
